SSL 凭证是互联网安全的基本因素。它们用于建立加密的连接，并允许在浏览器或用户的计算机和服务器或网站之间安全地传输数据。
Basic SSL (Domain Validated) Certificates are the easiest and most common type of SSL certificate. OV and EV Certificates also authenticate the identity of the company or organization that holds the certificate providing more trust to end users.
With our SSL certificate services*, you won't need to take manual steps to configure and deploy new certificates every year. We generate a renewal order automatically when your certificate nears the end of its validity. After payment, we will automatically configure, validate, and provision your new certificate for you.
* Your domain must be hosted through the same hosting provider who sold the SSL certificate, and the server must use cPanel, Plesk, or DirectAdmin.

非常适合敏感网页，包括电子商务，网上银行，帐户注册
